Application filed February 7, 1927.

This invention relates to a novel `adjustable or shiftable guide attachment for ruling` B machines.

My primary aim is to provide an attachment for a machine of this character, wherein the attachment is such in construction as to operate as a time saver, as well as a saver for material and labor.

An equally important object is to obviate the disadvantages of using shifting clamps, beams, rand guide cords after the pins are set- An advantage and purpose is to perfect an absolutely accurate guiding means for the sheet of paper, so, that the sheetmay be delivered evenly and uniformly to the inking pens, thus assuring proper registration of the lines. i y

A still further object is to provide a guide of this character which is adjust-able from a small fraction of an inch to approximately seven and one-half inches, and which is such that when it is once set, it cannot be accidentally moved unless readjusted by the oper ator.

An additional `object is to provide a struc ture of this kindwhich is characterized by compactness and convenience of arrangementof parts, so adjusted and related as to insure efficiency and practicability. n

Other features and advantages of the invention will become apparent from the following description and drawings.

In the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same `Figure l is a fragmentary top yplan view of a portion of a ruling pen machine showing the attachment (in dotted lines) associated therewith. e

Fig. 2 is an end view of the same.

Fig. 3 is a vtop plan view of the attachment per se, removed from the machine.

Fig. 4 is an enlarged detail section taken approximately upon the plane of the line 4-4 of Fig. 3, and

Fig. 5 is an enlarged detail sectional view taken approximately on the line 5-5 of Fig. 3.

Consideringnow the drawings indetail,

and confining attention first to the old partsy of a conventional type of ruling machine, it will be seen that the reference character `A designates lthe usual guide cord which co- ADJUSTABLE GUIDE FOR RULIITG MACHINES.

operates with thegrooved guide cord roll A part of the frame is represented at C and this is provided with a grooved guide cord roll bearing at D. The customary operating crank for turning the ruling niachine is indicated at E. AtF a portion of the frame is indicated, and at G is ay bolt for holding the frame. The character I-I represents a support for the customary feed board, the latter being represented by the reference character I.

The usual byk the reference character J. The dotted bolts K extend through the guide board, feed board, and feedboard brace, represented :by the reference character P. The guide board is represented at L. The reference character N (see Fig. l) is representative of an adjusting screw for the guideboard Astraight edge ld. In addition, O represents a part of the frame, and Q a pair of spaced formed in the feed board I.

The attachment or shiftable guide device, is attached to the under side of thev feed board L as best shown in Fig. y2. The device by itself however, as more plainly represented in Fig. 3, wherein it will be seen that the same comprises a pair ofL duplicate spaced parallel shafts l rigidly pinned at one end to a connecting strip 2, and fastened at the oppositeend to a similar but slightly longer connecting strip 3. I employ'a pair parallel slots of right angle brackets 4i to connectthestrip 2 to the feed board.

In this connection, I would statcthat I employ wood screws for this purpose, the brackets being suitably connected to lthe connecting strip or member `2. Similar brackets 5 are fastened to the member 3 and the horizontal portions thereof are slotted to form forks which are fastened to the bolts K which extend through the `brace bar P. These four parts `l, 2 and 3, form a framelike support for a carriage which is represented generally by the reference character 6. This carriage includes atravelling `bar 7 which has f its opposite ends slidably mounted on the shaft (l. To accomplish this, I form openings in the ends of this part 7 and extend the reduced Iend portions of the sliding sleevesvS through these openings the sleeves being slidably mounted on `the shafts l, l.

In this` connection, it will be noted that 3. The swivel mounting of the letty hand end oi the teed screw l() is shown 1n Figure,

o in dotted lines, while the corresponding mounting ot the opposite end oi" the same. screw is shown in Figure ll.

The inner end of the bushing l) is externally screw threaded, and a collar 11 is iitted onto the same to provide a connection between it and the travelling bar 7. l,Vhile considering the last named ligure, it will be noticed thata linurled linger nut 12 is pinned or otherwise rigidly secured to the ieed screw l() and it is obvious that by rotating this nut, the screw will rotate and will, thru the medium of the bushing 9, move the traveling bar T and its sleeves 8 back or i'orth on the shafts l, according to the direction of rotation of the nut.

Attention is now invited to the provision of the straight edge or shiftable guide elcment 13 which forms a part of the sliding carriage and which is connected thereto by means ot a pair oit upstanding standards 1l. As shown in Figs. it and 5, the upper ends of these standards have studs litting into sockets in the under edge ot the straight edge. This shiftable guide element i3 is in its normal position, disposed in abutting relation with the guide board straight edge M as shown for example in Figure l.

Also as shown better in Fig. 5, the traveling bar 7 is provided with vertical screw threaded holes through which an elevating screw l5 pass This screw is connected with standards lft and it is provided at its bottom with ahandle 16 and above this is a lock nut 17. It is obvious that by rotating the screw l5, the adjacent standard lle can be elevated in order to raise or lower the shi'ftable guide element 13.

iit this time, I would call attention to the i'act that this guide element is located above the top ot the feed board I and thatl the standards ilextend upwardly through the slots Q in this ieed board. Hence, as before stated. the guide can be adjusted trom a small traction of an inch to approximately seven and one-halt inches along the surface ot the feed board toward or from the guide board straight edge M.

Attention is invited to the fact that. when setting the pens to rule equally spaced unit columns, every other column is set. Therelore, it is necessary to run the sheet through the ruling machine the second time. liel'ore doing so, the straight edge olf the shil'table guide is moved back or iorth (depending upon the position ot the straight edge when starting), the distancey between columns 'tor second rum'iing. After ruliircr loose leal' sheets, from bindingI edge, reversing the saine to rule other side requires approximately ten seconds to adjust guide in order that the lines will register. Should changey in temperature cause sheets oi paper to contract or expand, it would not he. necessary to move the, clamps as under oridinary conditions. Shifting ot' the guide bach or forth will malte the lines register.

lt is belived that by considering the l'oregoing description in connection with the drawings, a clear understaiuliner ot the invention and construction, method oi' attachment, and operation will be clear. 'l`heretore, a more lengthy description is thought unnecessary.

1While the preierred embodiment o'l the invention has been shown and described, it is to be understood that minor changes coming within the field oi invention claimed may be resorted to it' desired.

Having thus described my invention, what I claim as new is"- l. In a structure ot the class described, in combination, a ruling machine embodying, among other parts, a feed Yboard, a. guide board associated therewith, and a supplemental manually adjustable guide and straight edge device, movable toward and from said guide board and across the top of said 'feed board, and manually atiljustable means for said supplemental guide being supported 'rom the under side of said feed board.
